STAMPING DEVICE Filed Feb. '7, '1927 atroz mm3 I Patented Oct. 8, 1929 Y UNTE 'STATES PETER GRABLER, OF ROCKY RIVER, OHIO sTAMPING Dnvrcn Application filed February 7, 1927. Serial No. 166,520.

My invention relates to stamping devices generally and Yparticularly to self inking stamping devices which have changeable type.

One of the objects of myinvention is to provide a simple, inexpensive, substantial, and eiiicient stamping device.

Another object of my invention is toy arrange theelements of a stamping device so that they can be made in quantity and assembled without causing binding between them and without requiring any fitting.

Another object of my invention is to provide a stamping device with means for tale ing up changes in the typelthereof.

Another object of my invention is to provide a lock means for the type adjusting means of a stamping device. f

Another object of my invention is to provide a cushioning means for the type ofk a stamping device near the juncture of the type and an adjacent member of the device.

Other ob'ects will appear or become apparent or o vious during the description of the device shown in the accompanying drawing.

In stamping devices, particularly in those which vare self inking, considerablel mechanism is necessary; this mechanismA in the prior devices gets out of ordereasilyand frequently due to the complicated structure used to attain that mechanismand to the continued pounding action thereon. The present invention aims'to provide a stamping device which is light in weight and which does not get out of Vorder easily.

In stamping devices, vparticularly those which have type on a band or ribbon, the continued use of the prior devices eventually changes the type, as the stretching of the ribbon for instance; this is an undesirable or disadvantageous feature. The present invention aims to prevent the stretching of the ribbon and changes or displacements of the t pe.

yIn stamping devices it is 4quite desirable and advantageous that the device can be manufactured as economically as possible. The present invention aimsto so form and arrange and relate members that they can be made easily and economically and assemi thereof. In order to retain alignmenty ofthe type on such a device it is necessary that the type on the carrier thereof is adjustable. Due to the continued pounding on such devices, the adjustment provided in prior devices does not stay in adjusted position. rlhe present invention aims to retain the adjustment of the type.` l v i In order to illustrate my invention, I have shown the same as embodied in a self inking hand stamp which has vtype on an endless band or ribbon. I am aware, however, that my invention vcan be applied to other devices. In the'y accompanying drawing Fig. l is a perspective view of a self inking hand stamp-ing device with changeable type, embodying the features of my invention. This .device is here shown in normal position of the elements with the operating j in other words, is here shown as if it was in stamping position in the device.

Fig. 3 is aperspective view of one of the floating members between the type frame and the type carrier of Fig. 1.

Fig. 4 is a perspective view of the type carrier of Fig. l and shows more clearly the one piece structure and formation thereof.

Fig. 5 is a section, taken in a vertical plane indicated bythe line 5-5 in Fig. l, and shows more clearly the relations of the elements.

Fig. 6 is a section,` takenv in a vertical plane indicated by the line 6-6 in Fig. 5 and' shows more'clearly the guide means and the relations between the type carrier and the type frame and the adjusting means between them.

Fig. 7 is a perspective view, partly in section, of the type cushioning means: between the type carrier and the band of type.

Similar reference characters refer to similar parts throughout the views.

The device shown in the accompanying drawing is a self inking hand stamping device having bands of type and comprises, principally, the main frame A, the operatingmember B, the type frame C, the type carrier D, and the type means E. y

The main frame A is formed of one piece of sheet metal with the end walls 10 and 11 and the top wall 12 with the bent edges 13 to form the channel or trough wherein the inking pad 14 is mounted.

The operating member B has the `handle 15 as well as other features 'usually found on such devices and necessary or convenient for the operation of the device and also has the legs 16 and 17 extending over the outside of the ends of the frame A.

In order to provide simplicity and inexpensive structure and to prevent parts from getting loose or otherwise getting out of order, I combine parts and form the combination of one p-iece of material which, naturally, does not get out of order and which can be made with dies which always produce the pieces as substantial duplicates'of each other and thereby eliminate the human element of error in assembling as well as in preparing the parts for assembling and also eliminate the necessity of fitting during the assembling or to do4 any other work thereon previous to the assembling and also eliminate all possibility of parts of an assembly get ting loose or shifting from their intended position since there are no parts.

In the present instance, the t-ype frame C is made of one piece of sheet metal and is formed with the base wall 18 having the opening 19 through it; the middle portion of this opening is provided to clear the type and each end of this opening has the guide walls 20,21, and 22. The flanges 23 are bentfrom the sides of the wall 18 to stiften the structure as rwell as to provide a means for abutting a surface to be printed upon in alignment with and in proper relation to the type- A The legs 24 are bent from the ends 'of the wall 18, each having the slot 25 and the round hole 26 through it.

The guide ears 27, comprising two oppositely disposedy pairs of ears facing each other, are bent inwardly from the legs 24 each ear having the hole 28 through it; the holes 28 in each pair of ears being in alignment.

In the present instance, the type carrier D is made of one piece of sheet metal and is formed with the guide members 29 each having the slot 30 through it and with the flanges 31 bent outwardly from one end of each member 29, each having the journal opening 32 through it, and with the inwardly curved portion 33 connecting the yother ends of the members 29 and forming the trough 34 with the open side thereof disposed outwardly from the carrier D. The edges of the guide members 29 fit slidingly between the respective of the ears 27 and between the guide walls 20 and 21 and are guided thereby when the frame C and thecarrier D are assembled. The connecting portion 33 extends through the opening 19 in the wall 18 of the frame C when the device is assembled.

` In the present instance, the type means E is of a usual structure having three endless type bands or ribbons with type thereon and the adjoining disks for individually adjusting each band as desired. The particular structure of the means E does not, in itself, form a part of the present invention except in so far as it is combined with or related to other parts or elements of the present invention.` One end of the type means E is mounted on the shaft 35 the ends of which are mounted in the respective of the guide portions 29.

A'floating member 36 is disposed between each pair of the ears 27'and each member 36 i has a lug 37 on two opposite sides thereof and extending into the respect-ive of the openings 28 in the ears 27 and also has an internally threaded hole 38 in alignment with the journal openings 32 through the flanges 31 when the frame and the carrier are assembled.

The lugs 37 are shown' rectangular and of the same thickness as the material of .which the member 36 is made. This arrangement is the most economical from a production standpoint since one` punching operation completes the formation of this member except the tapping of the hole 38. When it is desiredto provide leeway for the members 36 so that the same can adjust themselves in the ears 27, theholes 28 may be ymade larger than the `lugs 37. l Another expedient, although more expensive than the rectangular lug arrangement mentioned, is to make the lugs 37 and the holes 28 round so that the members 36'are journaled in the ears 27.

The walls 39 of the members 36 are spaced from and do not normally contact the inner faces of the ears 27; this arrangement permits the members 36 to float between the ears 27 and this floating feature can be augmented by the loose or by thejournaled lugs arranged as described above. Y

The screws 40 are threaded into the respective ones of the holes 38 in the members 36 and are journaled in the respect-ive ones of the journal openings 32 in the flanges 31 of the carrier D and the head of each screw has the serrations 41 and abuts the outside of the respective one of the flanges 31 on the carrier D.

The springs 42, coil springs in the present instance, are disposed over the respective ones of the screws 40; one end of each spring abutlmove the carrier D in the guides of the frame C and holds the flanges 31 resiliently against the underside of the heads on the screws 40.

The free ends 43 of the wire of the springs 42 extend through the holes 44 in the flanges 31' and engage the serrations 41. f

The trough 45 is disposed over and spa-ced from the trough 34 with the open side of the trough 45 facing the open side of the trough 34. The other end of the type band abuts the closed side of the trough 45.

In the present instance, the means for cushioning the pounding or blows on the type comprises the corrugated spring46 disposed in and between the two troughs and arranged so that the high points o-f the corrugations on one side of the spring engage the interior of the trough 34 and the high points of the corrugations on the other side of the spring engage the interior of the trough 45. This arrangement tends to separate the two troughs and thereby takes up all slack in the band type and also relieves the type band from receiving sharp shocks or blows or poundings during lthe operation and use of the device and thereby not only preserves the type band but also prevents the stretching thereof by eliminating the sharp pounding thereon.

A different kind of a spring, or a different kind of a cushioning means (as rubber for instance), or a different vstructure may be used to cushion the operating end of 'the type band.

One end of each of the links 47 is hinged vonto the main frame A and has a slot through it comprising the two straight and aligned portions 48 and 49 and the arcuate portion 50 connecting the straight portions. The pins 51 are fixed in the respective one of the links and extend inwardly and into the slot-s 25 of the legs 24.

The shaft 52 extends through the legs 16 and 17 of the member B, through the slots 53 in the end walls 10 and 11 of the member A, through the slots in the links 47, through the holes 26 in the legs of the member C, through the slots 30 in the guide members of the member D, and through the other end of the type member E.

This arrangement, aided bythe spring 54 in the tube 55, normally retains the operating portion of the type bands against the ink pad. When the member B is forced toward the member A, the shaft 52 is moved with it. Due to the shaft being retained in the holes 26 and in the type member E and being slidable in the slots in the links and in the slots 30 and 53, and due to the pins 51 being slidable in the slots 25, the downward VVmovement of the shaft 52, by means of the member B, rst imparts a straight downward movement to the member E due to the straight portions 48 of the slots in the links 47 to remove the operating portion of the member E straight from the inking pad,`then imparts a rotative movement tothe frame C and the carrier D and the member E and rotates these members half way around due to the pins 51 engaging ,the arcuate portions 50, and then imparts another straight downward movement to these members due to the straight portions 49 in the links so that the operating portion of the type band contacts the type squarely on the surface to be printed upon. Upon release of the member B, the above movement is reversed by means oft-he spring 54 and the operating portion of the type band again contacts the inking pad for the renewal of ink on the type.

The screws 40 may be manipulated to adjust the carrier D in the frame C and thereby adjust the face of the type in relation to the abutting edges of the flanges 23.

Since the members 36 can float in the frame C in my invention, all possibility of binding is eliminated between either the frame C or the carrier D or between the screws and tle frame C or the carrier D or both and this possibility ofl elimination is attained byl the usual fornfrationv operation of the members and without any additional cost above the usual production cost thereof.

Since my invention provides a lock means for the screws 40, there is no possibility of the screws moving-and destroying the adj ustment of the type during the usual pounding eects onthe type. The ends of the wire of the springs'resiliently engage the serrations in the heads of the screws and thereby hold the screws against rotation thereof during the use of the device but permit the screws tobe rotated by exterior means ywithout manipulating or otherwise paying any attention to the screw locking means. j

My invention provides vthe fewest possible parts the parts themselves formed for economical production; all parts formed and arranged so that they can be made economically and assembled economically; ioating means to prevent binding between the adjusting screws andthe type frame and the type carrier; cushioned abutment means for t-he type; and lock means for the adjusting screws to yretain the type in proper adjustment during the use of the devicebutpermittingthe manipulation of the adjusting screws without paying any attention to the lock means.
